Investigators said they began investigating Dominick Barbieri after a complaint by the aunt of another crossing guard, 27-year-old Desiree Santana.

Santana, who dated Barbieri in the past, said that sometime before March 2011, he told Santana he had a secret.

According to the arrest report, Santana told officials that Barbieri "liked to look at girls between the ages of 12 and 16 on the Internet." Barbieri also told Santana, "he fantasized about having sex with the young girls, however would never act upon his fantasies," the report said.

Santana said on several occasions at Barbieri's home, she observed him looking at photos of young girls in bathing suits and provocative clothing on his computer.

Officials said Santana told them she didn't say anything initially because Barbieri told her he would hurt or kill her if she told anyone.

A search of Barbieri's personal computer revealed downloaded images of nude children under the age of 18 that were obtained from several websites, the arrest report said.

Investigators said Barbieri admitted to them he had been downloading the pictures for at least six months and masturbated to the photos. He told officials "he thought it was OK and legal to look at photographs of nude children, exposing their genitals on modeling sites," the report said.

Barbieri admitted to authorities he fantasized about a fifth-grade girl he saw at the bus stop while at work. He said she could have passed for a high school girl. Authorities said Barbieri told them he fantasized about sex with the fifth-grader.

Barbieri has been employed with the Orange County Sheriff's Office since Nov. 2006, he was fired on Wednesday.

The Orange County Sheriff's Office said they are investigating and more charges are pending.
